One component of the PHDCN was the Longitudinal Cohort Study, which
was a series of coordinated longitudinal studies that followed over
6,000 randomly selected children, adolescents, and young adults, and
their primary caregivers over time to examine the changing
circumstances of their lives, as well as the personal characteristics,
that might lead them toward or away from a variety of antisocial
behaviors. Numerous measures were administered to respondents to
gauge various aspects of human development, including individual
differences, as well as family, peer, and school influences. The
Deviance of Peers was a self-report interview that obtained
information about peer involvement in conventional and delinquent
activities. Information about peer pressure to use drugs and/or
alcohol was also collected.

Access to these data is restricted. Users interested in obtaining these data must complete a Restricted Data Use Agreement, specify the reasons for the request, and obtain IRB approval or notice of exemption for their research.

Universe:

caregivers, living in the city of Chicago in 1994.

Methodology

Study Purpose:

Project on Human Development in Chicago
Neighborhoods

The Project on Human Development in Chicago
Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of
how families, schools, and neighborhoods affect child and adolescent
development. It was designed to advance the understanding of the
developmental pathways of both positive and negative human social
behaviors. In particular, the project examined the causes and pathways
of juvenile delinquency, adult crime, substance abuse, and
violence. At the same time, the project provided a detailed look at
the environments in which these social behaviors took place by
collecting substantial amounts of data about urban Chicago, including
its people, institutions, and resources.

Longitudinal
Cohort Study

One component of the PHDCN was the
Longitudinal Cohort Study, which was a series of coordinated
longitudinal studies that followed over 6,000 randomly selected
children, adolescents, and young adults, and their primary caregivers
over time to examine the changing circumstances of their lives, as
well as the personal characteristics, that might lead them toward or
away from a variety of antisocial behaviors. The age cohorts include
birth (0), 3, 6, 9, 12, 15, and 18 years. Numerous measures were
administered to respondents to gauge various aspects of human
development, including individual differences, as well as family,
peer, and school influences.

Deviance of Peers

The data in this collection are from Wave 1 of the Longitudinal
Cohort Study, which was administered between 1994 and 1997. The data
files contain information from the Deviance of Peers protocol. The
Deviance of Peers was a self-report interview that obtained
information about peer involvement in conventional and delinquent
activities.

Study Design:

Project on Human Development in Chicago
Neighborhoods

The city of Chicago was selected as the
research site for the PHDCN because of its extensive racial, ethnic,
and social-class diversity. The project collapsed 847 census tracts in
the city of Chicago into 343 neighborhood clusters (NCs) based upon
seven groupings of racial/ethnic composition and three levels of
socioeconomic status. The NCs were designed to be ecologically
meaningful. They were composed of geographically contiguous census
tracts and geographic boundaries, and knowledge of Chicago's
neighborhoods were considered in the definition of the NCs. Each NC
was comprised of approximately 8,000 people.

Longitudinal
Cohort Study

For the Longitudinal Cohort Study, a
stratified probability sample of 80 neighborhoods was selected. The 80
NCs were sampled from the 21 strata (seven racial/ethnic groups by
three socioeconomic levels) with the goal of representing the 21 cells
as equally as possible to eliminate the confounding between
racial/ethnic mix and socioeconomic status. Once the 80 NCs were
chosen, then block groups were selected at random within each of the
sample neighborhoods. A complete listing of dwelling units was
collected for all sampled block groups. Pregnant women, children, and
young adults in seven age cohorts (birth, 3, 6, 9, 12, 15, and 18
years) were identified through in-person screening of approximately
40,000 dwelling units within the 80 NCs. The screening response rate
was 80 percent. Children within six months of the birthday that
qualified them for the sample were selected for inclusion in the
Longitudinal Cohort Study. A total of 8,347 participants were
identified through the screening. Of the eligible study participants,
6,228 were interviewed.

For all cohorts except 0 and 18,
primary caregivers as well as the child were interviewed. The primary
caregiver was the person found to spend the most time taking care of
the child. Separate research assistants administered the primary
caregiver interviews and the child interviews. The primary method of
data collection was face-to-face interviewing, although participants
who refused to complete the personal interview were administered a
phone interview. Interviews were conducted in Spanish, English, and
Polish. In Wave 1 the complete protocol was translated into Spanish
and Polish. An interpreter was hired for participants who spoke a
language other than English, Spanish, or Polish. Depending on the age
and wave of data collection, participants were paid between $5 and $20
per interview. Other incentives, such as free passes to museums, the
aquarium, and monthly drawing prizes were also included.

Interview protocols included a wide range of questions. For
example, some questions assessed impulse control and sensation-seeking
traits, cognitive and language development, leisure activities,
delinquency and substance abuse, friends' activities, and
self-perception, attitudes, and values. Caregivers were also
interviewed about family structure, parent characteristics,
parent-child relationships, parent discipline styles, family mental
health, and family history of criminal behavior and drug use.

Deviance of Peers

The full version of Deviance of
Peers was a 36-item self-report interview that obtained information
about peer involvement in conventional and delinquent activities and
was administered to participants in Cohorts 9 to 18. Information about
peer pressure to use drugs and/or alcohol was also collected.

Sample:
Stratified probability sample.

Weight:
none

Mode of Data Collection:
face-to-face interview,
telephone interview

Description of Variables:
The data files contain information regarding the
participant's peer group involvement in school and after school
activities and in various delinquent acts or crimes, such as truancy,
theft, assault, weapon use, illegal drug use, and sexual behavior. In
addition, the participant was asked how often the peer group pressured
the participant to engage in drinking or drug use.

Response Rates:

The overall response rate for Wave 1 of the
Longitudinal Cohort Study was 75 percent or 6,228 participants. The
response rates by cohort were:

76.2
percent (1,269) for Cohort 0

76.6 percent (1,003) for
Cohort 3

75.0 percent (980) for Cohort 6

75.9
percent (828) for Cohort 9

74.3 percent (820) for Cohort
12

71.6 percent (696) for Cohort 15

70.3 percent
(632) for Cohort 18

Presence of Common Scales:

Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:

Performed recodes and/or calculated derived variables.

Checked for undocumented or out-of-range codes.
